Is a Thermostat Replacement in Your Future? 

Thermostats are an important part of your home’s infrastructure that you may not think much of until they experience an issue. Often, older thermostats are working past their estimated lifespan, and that is when they begin to show signs they may warrant a replacement. 

No matter the age of your thermostat, look out for: 

  • Inaccurate Readings: The device displays a temperature that doesn’t match the actual air in the room.
  • Unresponsive Interface: The screen stays blank or buttons fail to trigger the air conditioner.
  • Short Cycling: Your HVAC system turns on and off too frequently due to faulty sensor data.
  • High Energy Bills: An outdated controller causes your unit to run longer than necessary.
  • Obsolete Technology: Older manual sliders lack the precision of modern digital controls.

Our Thermostat Services

We sync your controls with your heating and cooling hardware to ensure every signal reaches your unit instantly.

Thermostat Repair

We diagnose communication issues between the thermostat and the HVAC control board. Our technicians identify loose wiring and replace faulty internal components to get your system back online. If a repair is not cost-effective, we provide clear options for a modern upgrade.

Maintenance & Tune-Ups

During a standard maintenance visit, our team verifies that your thermostat is leveled and calibrated. We check for software updates on smart models to prevent system strain and ensure peak efficiency.

Installation & Replacement

We install a wide range of systems, including programmable and Wi-Fi-enabled smart thermostats. Our process involves precise wire mapping to ensure your multi-stage heating and cooling functions work correctly.

I had a wonderful experience when RS Andrews crew came to do a total hvac duct cleaning. It was included as part of my purchase package of a new hvac system. They arrived exactly on time, instantly started the work, efficiently and quickly. Everything they were doing was explained to me beforehand and when the job was finished they vacuumed and left the place cleaner than when they found it. I strongly recommend RS Andrews to everyone. Great staff too!

RS Andrews just completer a full 12ft+ tall attic wall and ceiling lay in insulation for us. The techs were on time, courteous, and faster than anticipated and left the job site impeccably clean! Could not be more thrilled. Wish we had not waited so long to do this, the heat reduction for the hot months is already palpable. ❤️
